Background/Aims: Radiation therapy is an important treatment for thoracic cancer; however, side effects accompanied with radiotherapy lead to limited tumor control and a decline in patient quality of life. Among these effects, radiation-induced lung injury (RILI) the most serious common. Hence, effective remedy RILI needed. Mesenchymal stromal cells (MSCs) are multipotent adult stem that have been demonstrated be some disease caused by tissue damage. However, unlike other injuries, received...
This work aims to elucidate how the branching effect of macromonomer influences polymerization, structural features, and solution properties ABn long-subchain hyperbranched polymers (LHPs). Our result reveals that compared with linear AB2 macromonomers, star AB3 macromonomers in suppression chain extension, enhancement self-cyclization during preparation LHPs by "click" due branching-enhanced steric hindrance effect. The combined triple-detection SEC stand-alone LLS studies unfractionated...
In this paper, high-speed photography was employed to experimentally study the high-speed, shallow-angle water entry of cylinders. By varying density, length–diameter ratio, and launch speed cylinders, three typical trajectories were observed: arc, S, ricochet trajectories. This examined cavity evolution, motion trajectory, force state, stability cylinders under these Additionally, influence each cylinder's ratio density on its during explored. The experimental results indicated that impact...
Three-dimensional (3D) carbon-based scaffolds have rapidly risen in tissue engineering due to the excellent conductivity and unique topological structures. For specific vivo application, it is desirable maintain rigidity improve toughness of response compression force from surrounding tissues. In light combined advantages graphene hydrogels, we here construct a 3D composite scaffold consisting foam (GF) laminarin hydrogel (LAgel). The was fabricated by immersing GF an LA precursor followed...
Internal dynamics of polymer chains is one the most important fundamental problems in physics. This work reports first example a dynamic light scattering (DLS) study internal motions well-defined ultralong comb-like dilute solutions under good solvent conditions. Using two well-characterized model samples with controlled parameters and narrow distributions (Mw/Mn ≈ 1.30 Mw 107 g/mol), asymptotic behavior reduced cumulant [Γ* = Γ(q)/(q3kBT/η0)], number relaxation modes Γ(q) distribution...
We herein reported colossal dielectric constant (CDC) behavior in GaAs single crystals.
V-type (<bold>B</bold>∼∼<bold>A</bold>∼∼<bold>B</bold>) and Y-type (<bold>A</bold>∼∼∼∼<bold>B</bold><sub>2</sub>) macromonomer approaches are two of the most widely adopted synthetic methodologies for preparation long-subchain hyperbranched polymers (LHPs) with a controlled subchain length.
We aim to clarify how the chain length influences critical flow rate (qc) for flexible linear chains translocating through cylindrical nanopores in whole range (9.5 > R/r 1.0), where R and r represent size pore size, respectively. By studying translocation behavior of both mono- polydisperse polystyrenes 20 nm nanopores, we have, first time, experimentally revealed that there exist two different regimes, i.e., strong moderate confinement regimes. In regime (R/r λ*), qc is found be...
A biocompatible conductive composite electrode GN–PPy–FL can realize controlled release of a drug model triggered by low voltages.
Abstract The magnetoresistance (MR) of spin values usually displays a symmetric dependence on the magnetic field. An antisymmetric MR phenomenon has been discovered recently that breaks field symmetry and potential to realize multi-bit memory. In this work, we report controllable switch between MRs propose memory performance in Fe 3 GeTe 2 (FGT)/graphite/FGT trilayer with modified vertical geometry. Via investigating evolution depending spatial distribution, current direction, magnetization...
The magnetic proximity effect enables the incorporation of properties into non-magnetic materials, thereby achieving high-performance electronic devices. 5d perovskite-oxide iridates provide a versatile platform for investigating competing states due to their strong spin–orbit coupling. By conventional 3d transition-metal oxide ferromagnets, originally paramagnetic SrIrO3 is expected exhibit exotic phenomena. In this study, we report emergence perpendicular net moment and an unprecedented...
Organic matrixes of commercial dental composites generally consist diluent such as triethylene glycol dimethacrylate (TEGDMA) to decrease viscosity. However, the increasing dilution exhibited adverse effects higher polymerization shrinkage and water uptake resin materials. Therefore, viscosity matrix should be low possible fabricate with a minimum content diluent. To overcome high 2,2-bis[4-(2-hydroxy-3- methacryloyloxypropoxy) phenyl] propane (Bis-GMA) caused by hydrogen bonding between...
This work shows how the unique slow diffusion and multi-charge properties of polyelectrolyte ligand dominate catalytic mechanism for water oxidation catalysts.
Internal dynamics of flexible polymer chains is one the most important fundamental problems in physics. Although numerous efforts have been devoted to understanding internal for linear polymers, little attention was paid branched systems. This work aims elucidate how branching effect quantitatively influences motions long-subchain hyperbranched polymers dilute solution. By light scattering study four polystyrene samples with controlled patterns and low polydispersities (Mw/Mn < 1.40 Mw ∼ 107...
Following our recent work on AB3 macromonomer systems (Macromolecules, 2019, 52, 1065–1082), this focuses AB4 to further explore the effect of branching structural features and solution properties long-subchain hyperbranched polymers (LHPs). Compared with ABn macromonomers (n < 3), results reveal that tend undergo less interchain coupling but more intrachain self-cyclization during "click" polyaddition process. Via triple-detection SEC characterization resultant LHPs, both intrinsic...
Conformation statistics of macromolecules in dilute solution is one the fundamental issues polymer physics. Herein, we experimentally explore average conformation model randomly hyperbranched chains composed uniform subchains near θ point (Tθ,hyper). We have, for first time, verified size-mass scaling relation Tθ,hyper. Quantitatively, Flory exponent (ν) <R> ∼ NtνNbμ determined to be ν ≈ 0.46 good solvent toluene and 0.40 ≤ 0.47 theta cyclopentane. Our result agrees well with theoretical...
The Topological Hall Effect (THE) has been considered a hallmark of magnetic skyrmions in SrRuO3 single films and heterostructures. Alternative interpretations suggest that the THE-like anomalies could also originate from multi-channel anomalous effects (AHEs) induced by structural inhomogeneity. Here, we reveal another type anomaly was rarely reported previously. By scanning minor loops resistivity ultrathin films, demonstrate increased saturation reversed polarity with decreasing field...
